Behçet's syndrome is a systemic vasculitis characterized by recurrent oral ulcers, skin lesions, and ocular inflammation. In recent years, an increasing number of clinical cases with coexistence of MDS and Behçet's syndrome have been reported, suggesting a potential pathological relationship between these conditions. Abnormal immune cell activation, dysregulated cytokine secretion, and cytogenetic alterations are thought to play critical roles in the pathogenesis of MDS combined with Behçet's syndrome. Currently, treatment strategies for MDS combined with Behçet's syndrome are primarily individualized and include immunosuppressive therapy, cytotoxic drug therapy, targeted therapy, and hematopoietic stem cell transplantation. However, due to the limited number of case reports and insufficient research on the underlying mechanisms, selecting appropriate treatment options remains challenging. This article reviews the pathogenesis and interrelationships of MDS combined with Behçet's syndrome and summarizes recent advancements in treatment strategies, providing a reference for clinical management and further researches on related mechanisms.</p>","PeriodicalId":24007,"journal":{"name":"Zhejiang da xue xue bao.

The service provisions, including ensuring daily activities, preventive healthcare, and satisfying spiritual comfort, were compared among the groups. The family friendly care environment was evaluated with the Family Function Scale and assistance of daily activities, financial support and emotional comfort. The social friendly care environment was measured with the revised WHO recommended age-friendly city environmental framework, including accessibility guarantee environment, information dissemination environment, social participant environment, and life security environment. After controlling for covariates such as sociodemographic, elderly care status, and health risk characteristics, the impact of environment on the effectiveness of service provision of LTC insurance was explored by multiple logistic regression analysis. The mediating and moderating effects were tested to explore the role of age-friendly care environment. A fixed effects model was used to test the service provision effects of LTC insurance policy.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Disabled elderly with LTC insurance had a higher proportion of their preventive health care and spiritual comfort needs met. Additionally, a multifactorial analysis found a significant positive association between LTC insurance and meeting the spiritual comfort needs.

Ferroptosis is a form of cell death in response to metal pollutant exposure and it is closely related to oxidative stress, iron metabolism and lipid peroxidation. Recent studies have revealed that ferroptosis plays a significant role in the neurotoxicity induced by metals such as lead, cadmium, manganese, nickel, and antimony. Lead exposure triggers ferroptosis through oxidative stress, iron metabolism disorder and inflammation. Cadmium can induce ferroptosis through iron metabolism, oxidative stress and ferroptosis related signaling pathways. Manganese can promote ferroptosis through mitochondrial dysfunction, iron metabolism disorder and oxidative stress. Nickel can promote ferroptosis by influencing mitochondrial function, disrupting iron homeostasis and facilitating lipid peroxidation in the central nervous system. Antimony exposure can induce glutathione depletion by activating iron autophagy, resulting in excessive intracellular iron deposition and ultimately causing ferroptosis.
